UNA cojinete de giro, también conocido como rodamiento de anillo giratorio o rodamiento de plataforma giratoria, es un tipo especializado de rodamiento de elementos rodantes diseñado para soportar ejes, radial, y cargas de momento simultáneamente. Los rodamientos giratorios se utilizan comúnmente en aplicaciones que requieren movimiento de rotación., como grúas, excavadoras, turbinas de viento, y otra maquinaria pesada. The working principle of a slewing bearing involves its design, components, and the way it accommodates various loads.
How a slewing bearing works
Components of a Slewing Bearing
Canalizaciones: Slewing bearings consist of two rings, an inner ring and an outer ring, with raceways on both sides. These raceways are typically circular tracks along which the rolling elements move.
Rolling Elements: Los elementos rodantes, often balls or rollers, are positioned between the inner and outer raceways. They facilitate smooth rotation by reducing friction between the rings.
Cage or Spacer: In some slewing bearing designs, a cage or spacer is used to separate and maintain the proper spacing between the rolling elements. This helps ensure even load distribution.
Slewing Bearing Working Principle
Load Transmission
When external loads, including axial, radial, or moment loads, are applied to the slewing bearing, these loads are transmitted through the rolling elements to the raceways.
Axial Load Handling
The axial load is supported by the contact between the rolling elements and the raceways in the axial direction. This allows the bearing to withstand forces acting parallel to the axis of rotation.
Radial Load Handling
Radial loads are supported by the contact between the rolling elements and the raceways in the radial direction. This enables the bearing to handle forces acting perpendicular to the axis of rotation.
